3.1 Linux labels-2.c Regression

[Jeffrey Oldham]

Last night's gcc 3.1 i686-pc-linux-gnu regression tests showed new
regressions for

  FAIL: gcc.c-torture/compile/920501-1.c,  -O0  
  FAIL: gcc.c-torture/compile/labels-1.c,  -O0  
  FAIL: gcc.c-torture/compile/labels-2.c,  -O0  
  FAIL: gcc.c-torture/compile/labels-2.c,  -O1  
  FAIL: gcc.c-torture/compile/labels-2.c,  -O2  
  FAIL: gcc.c-torture/compile/labels-2.c,  -O3 -fomit-frame-pointer  
  FAIL: gcc.c-torture/compile/labels-2.c,  -O3 -g  
  FAIL: gcc.c-torture/compile/labels-2.c,  -Os  

Are you also seeing these regressions?
